Network reinforcement data request - Data sheet. This document contains network reinforcement data to help inform the assessment of network reinforcement costs at PR24. You can access the accompanying Network reinforcement - supporting guidance document in the publications section of our website. The Network reinforcement - supporting guidance document accompanies an information request that will collect additional network reinforcement data from incumbent water and wastewater companies, to support cost assessment of this expenditure at PR24. The data request has been discussed extensively with water companies and reflects a direct ask from water companies to consider additional data collection in our approach to growth expenditure and cost drivers. We are not intending to use the information for the purpose of setting reconciliation adjustments, due to endogeneity issues.
